A personality test aims to describe aspects of a person's character that remain stable throughout a person's lifetime.
A model of personality were first posited by Greek philosopher/physician Hippocrates. The 20th century heralded a new interest in defining and identifying separate personality types, in close correlation with the emergence of the field of psychology.
As such, several distinct tests emerged; some attempt to identify specific characteristics, while others attempt to identify personality as a whole.
Critics have raised issues about the ethics of administering personality tests, especially for non-clinical uses.
